On September 22 2017, the interplanetary probe OSIRIS-REx will fly past the Earth. The Earth will give it a "gravity assist" and put it on a trajectory to reach the asteroid Bennu. If you know where to look and live in the right part of the world, you will have a chance to see it through binoculars or a telescope.
